Additional tests were still being performed on other materials collected from the crime scene, including sinks and a section of carpeting from Strauss-Kahn’s hotel room, the AP reported.

The DNA is the first evidence tying Strauss-Kahn to the maid, but may be used by his lawyers in a defense strategy. At a hearing last week, attorney Benjamin Brafman said that forensic evidence from the hotel room was “not consistent with a forcible encounter,” suggesting that any sexual contact between the two was consensual. Brafman declined to comment on the DNA tests.

Strauss-Kahn resigned from his job as managing director of the IMF on Wednesday and is being held on house arrest in a lower Manhattan apartment rented by his wife.
